People get WAY too technical with these damn hinges. Here's all you need to do:

Put a pin through the center of the hinge and install them into the stab/ rudder/ wing/ whatever.

Add the control surface.

Remove the pin.

Add 4 drops of THIN CA to the top and bottom of each hinge.

That's IT! I have CA hinges that are 10 years old with no signs of any problems. The slight amount of pressure they put on the servo is NOTHING compared to the pressure applied to the servo from the airflow over the control surface. So don't worry about it!
